Arsenal's manager, Mikel Arteta, emphasised the need for a decisive performance against Sporting to end their poor away form in the Champions League. Arsenal have not won in their last four European matches and recently lost 1-0 to Inter Milan at San Siro. Currently, they are 12th in the new 36-team format, where only the top eight advance directly to the last 16.
Arteta highlighted that improving their away performances is crucial for success in Europe's premier club competition. "It's certainly something we have to improve. We have the right steps, and looking back at the way we played against Inter, we dominated the game and should have won," Arteta stated during a news conference on Monday. "But the reality is you have to make it happen, and we didn't."

The upcoming match against Sporting marks their seventh encounter in European competitions. The Portuguese team has yet to secure a win over Arsenal, with four draws and two losses in previous meetings. Despite this, Sporting is having an impressive season, remaining unbeaten with 10 points and recently defeating Manchester City 4-1.
Sporting's recent success comes despite losing former manager Ruben Amorim to Manchester United. Arteta acknowledged that facing such a strong opponent presents both a challenge and an opportunity for Arsenal to boost morale. "The run they are on is incredible," he said. "It tells you it's not only about their qualities but their ambition and the team energy they have."
Arteta stressed that Arsenal must seize this chance to make a statement by playing confidently against Sporting. "To come here tomorrow, make a statement, and show that we are capable against this kind of opponent by being ourselves and winning the game," he remarked.
Arteta also reflected on Arsenal's current standing in the league table. "We wanted to be higher (in the standings), but it's the position we are in right now," he admitted. He emphasised that playing strategically will give them a chance to win quickly.
The match offers Arsenal an opportunity to demonstrate resilience and efficiency in front of goal. Arteta believes that being ruthless and efficient is essential for success: "Those steps are what we need to take next - be ruthless and much more efficient in the opposition box."
This game represents a significant opportunity for Arsenal to regain momentum in Europe by overcoming Sporting's formidable challenge.
